A study on the venom yield of snakes from Argentina over a three year period was carried out on adult specimens of Bothrops alternatus (n = 74); Bothrops neuwiedii (n = 127); Bothrops ammodytoides (n = 30); Bothrops moojeni (n = 14); Bothrops jararaca (n = 14); B. jararacussu (n = 6); Crotalus durissus terrificus (n = 120) and Micrurus spp. (n = 6) as well as with 12 specimens of newborn C. d. terrificus kept in captivity. While for each species there was a positive correlation between venom yield and number of snakes milked, the correlation with the snake's body weights after individual milkings was even better, suggesting that the size of the snakes is more important in determining the venom yield than the number of snakes milked or the specimen's sex. Individual milkings indicated that, in addition to the snake size, when the amount of venom is normalized per 100 g body weight there is a species specific difference in venom yield. It follows the order B. jararacussu > B. moojeni approximately = B. jararaca approximately = B. alternatus > B. neuwiedii> Micrurus spp approximately = B. ammodytoides> C. d. terrificus. Although the venom yield per 100 g body weight of newborn C. d. terrificus specimens is 2-fold higher than that of adults, no correlation was observed between venom yield and body weight.
对阿根廷蛇类三年期间的毒液产量进行了一项研究，研究对象包括成年的交替锯鳞蝰（n = 74）、纽氏锯鳞蝰（n = 127）、沙氏锯鳞蝰（n = 30）、穆氏锯鳞蝰（n = 14）、巴西矛头蝮（n = 14）、大巴西矛头蝮（n = 6）、杜氏变色蜥（n = 120）和珊瑚蛇属（n = 6），以及12只圈养的杜氏变色蜥幼蛇。虽然对于每个物种，毒液产量与挤毒蛇的数量之间存在正相关，但与每次挤毒后蛇的体重之间的相关性更好，这表明蛇的大小在决定毒液产量方面比挤毒蛇的数量或标本的性别更重要。个体挤毒表明，除了蛇的大小外，当毒液量按每100克体重进行标准化时，毒液产量存在物种特异性差异。其顺序为大巴西矛头蝮>穆氏锯鳞蝰≈巴西矛头蝮≈交替锯鳞蝰>纽氏锯鳞蝰>珊瑚蛇属≈沙氏锯鳞蝰>杜氏变色蜥。虽然杜氏变色蜥幼蛇每100克体重的毒液产量比成年蛇高2倍，但未观察到毒液产量与体重之间的相关性。
